Embodiment Construction

[0046] Specific embodiments of the present invention are described below in conjunction with accompanying drawing:

[0047] The unmanned ship in this embodiment includes a state perception module and a cognitive module.

[0048] The state perception module includes a shore-based command interaction module and a ship-borne sensor data acquisition module, which is used to collect and receive various data suitable for anchoring from shore-based and ship-borne equipment.

[0049] The cognitive module is integrated with an anchorage expert knowledge base, which can process and analyze the anchoring data collected by the state perception module, so as to realize real-time cognition of the state parameters of shipboard equipment and comprehensive cognition of the overall situation of anchoring. Among them, the anchorage expert knowledge base is formed based on the experience of the captain, the existing data files of the anchorage, and the investigation of the unknown anchorage.

Abstract

The invention discloses an autonomous anchor dropping control method and system of a driverless ship. Whether anchoring is appropriate or not is judged according to the environment state of the selected anchor ground, the state of the ship, the weather and sea conditions, the actual environment and the state of the ship are judged according to the range where parameters belong, anchor dropping isconducted by selecting different anchor dropping modes and methods under different situations, the optimal anchor dropping effect is achieved, and intelligent anchor dropping of the unmanned ship is achieved. Autonomous anchor dropping is conducted through anchor dropping equipment, artificial intervention can be reduced, the anchor dropping efficiency is improved, quick and accurate anchor dropping is achieved, and safety of the ship within the anchoring time is improved.

Description

technical field [0001] The invention belongs to the technical field of anchoring operation of unmanned ships, in particular to a control method and system for autonomous anchoring of unmanned ships. Background technique [0002] Ship anchoring is a state of motion in which the ship is firmly controlled within a certain range by using the gripping force of the anchor and the anchor chain. Autonomous anchoring operation requires the use of sensors to feed back a series of signals of the navigation environment and the ship's own state, and convert them into the signals required by the anchoring system, and the anchoring system performs autonomous anchoring according to the signals. The existing autonomous anchoring system mainly uses ship power to control the ship and cooperates with manual operation to anchor, which is not suitable for long-term navigation of large unmanned ships. It can only meet fixed-point work, reduce labor intensity, and cannot achieve true autonomous anc...
